Matrix multiplication is an efficient algorithm that can optimize some one-dimensional recursion to log(n), and can also find path schemes, etc., so it is an extremely applicable algorithm.Matrix is one of the basic concepts in linear algebra.An m×n matrix is an array of m×n numbers arranged in m rows and n columns.Because it brings together a lot of data compactly, sometimes it is easy to express some complex models.Matrix multiplication looks strange, but it is actually very useful and widely used.
Matrix A =
1;4
2; 3
Matrix B =
5; -2
2; 2
Click "Calculate" to output the result
A x B =
1x5 + 4x2; 1x-2 + 4x2
2x5 + 3x2; 2x-2 + 3x2
A x B =
13; 6
16; 2
